To find the slope (and the y-intercept), we need to rearrange the equation to slope-intercept form: y=mx+b, where m = slope and b = y-intercept.
2y+3x-5 = 0
2y = -3x + 5
y = -(3/2)x + 5/2
So we know that the slope of the line is -3/2 and the y-intercept is (0, 5/2).
Statement 1 tells us that the y-intercept of q is NOT (0, 5/2), so this cannot be the equation. Sufficient.
Statement 2 tells us that the slope of q is NOT -3/2, so this cannot be the equation. Sufficient.
The correct answer is D.
